Successful transcatheter management of Palmaz Stent embolization after superior vena cava stenting

A 34-year-old patient with benign superior vena cava syndrome (SVCS) was treated with thrombolytic therapy, balloon angioplasty, and placement of two peripheral Palmaz stents. Embolization of one stent to the right atrium occurred 10 min after successful implantation. This serious complication was successfully managed by percutaneous transcatheter technique with retrieval from the right atrium and subsequent deployment into the right external iliac vein of the lost stent. Complete resolution of SVCS symptoms occurred within 24 hr and moderate superior vena cava restenosis was successfully dilated 8 months later. At 12-month follow-up the patient continues to be asymptomatic
